摘要：
In this work, TiO2 (0-50 vol%) nanoparticles (25 nm) were added to a 11.7Li(2)o 12.6ZrO(2). 68.6SiO(2). 7.1Al(2)O(3), LZSA (4 mu m) glass-ceramic matrix to prepare composites in order to investigate the influence of TiO2 on the sinterability, crystallinity and some properties to obtain information to design materials for low temperature co-fired ceramics (LTCCs) applications. The sintered composites (700-1000 degrees C/30 min) with relative densities between 95% and 98%, showed beta-podumene,TiO2 and Li2TiSiO5 as main crystalline phases. The maximum bending strength (235 +/- 84 MPa) was achieved for composites with 40% TiO2 sintered at 1000 degrees C/30 min. The coefficient of thermal expansion increased linearly with the concentration of TiO2, i.e., 3.5 x 10(-6) C-1 for 0% TiO2 and 9.5 x 10(-6) C-1 to 100% TiO2. The values of thermal conductivity were low and increased with the increase of the volumetric fraction of TiO2, reaching a maximum (3.30 W/mK) for samples (40% TiO2) sintered at 1000 degrees C/30 min. The measurements of electrical conductivity indicate that the obtained materials are electrical insulators (similar to 10(-10) S cm(-1)). (c) 2014 Elsevier Ltd and Techna Group S.r.l.
